Application filed November 14, 1919. Serial No. 338,074.

T all/whom t 'may concern:

Be it known that I, Ninils I). J. C. CARLS- LUND, a citizen of the United States, residing at West New York, in the countyof Hudson and State of-New Jersey, have invented certain new and useful Improvements in Antislipping Devices for Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same..

rIhis invention relates to shoe attachments and the primary object of the invention is to provide an improved device adapted to be attached to a shoe to prevent slipping of the shoe on a slippery surface, thereby facilitating the walking on ice and the like. n Y Another object of the invention is to provide an improved anti-skidding device for shoes, which can be readily and quickly placed on or removed from a pair o f shoes and prevented from accidental displacement while on the shoes.

A further obgect oi the inventionis -to provide an improved anti-slipping device for shoes embodying longitudinal andtransverse chains adapted to provide gripping means and means for holding said chains in operative position on a shoe.

A still further object of the invention is to provide an improved anti-skidding device for shoes of the above character, which is durable and eiiicient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

l/iith these and other objects in view, the 4g invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more fully described, claimed and illustrated in the accompanying drawings forming a part thereof, in which: 4.5 Figure l is a side elevation of the improved device showing the same attached to a shoe,

Fig. 2 is a bottom plan view of the same, and 5c Fig. 3 is a detail perspective view of the heel attaching plate.

Referring to the drawings in detail, where-` in similar reference characters designate corresponding parts throughout the several views, the numeral 1 generally indicates the improved anti-skid attachment for shoes which is shown attached to a shoe of the ordinary and preferred construction including the sole 3 and the heel 4:. The improved attachment l is formed from chain sections and includes the outer chain section 5, which extends around the edge of the sole and terminates at the instep portion-of the shoe.

The side chains 5 are connected by transverse chains 6 as clearly shown in Fig. 2 65 of the drawings. The chains 5 and 6 are adapted to engage the lower surface of the sole and are held against downward movement by an upper chain 7 which extends in parallel relation to the chains 5 and is positioned around the upper edge of the sole, and the chains 5 and 7 are connected by depending links 8. f

`The attachment l also includes a heel section 9, which includes plate l0, which is adapted to embrace and extend around the outer surface of the heel. The inner surface of the arcuate plate 10 at the rear eiid thereof is provided with inwardly extending sharpened teeth ll which 30 4are adapted to bite into the heelto prevent*N displacement of the arcuate plate. The forward ends of the arcuate plate 10 are bent back to provide eyes 12, in which are secured the rear terminals of contractile coil 35 Y springs 13, which have their forward terminals secured to the ends of the chain 8.

The contractile coil springs 13 hold the arcuate plate l0 in correct position on the heel and draw the same forwardly and draw the chain 8 rearwardly, and into tight engagement with the forward portion of the shoe, and prevent accidental displacement of the device. Cross chains 14 extend transversely across the heel and have their terminals connected to the lower side edges of the arcuate plate 10, and these cross chains 14 are connected together at their central portions by a relatively small chain l5.

It is a well known fact that chains provide an exceptionally durable and efficient means for preventing slipping on a wet or icy surface, and from the foregoing description, it can be seen that an improved device embodying chains as an anti-skidding element is provided for shoes, which can be readily and quickly applied to shoes of all descriptions and sizes and effectively prevented from accidental displacement.

In practice, I have found that the form an arcuate attaching 75 of my inventiom'illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment, is the 'most eilicient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportionand arrangement of partsrmay be resorted to, when required without sacrificing any of the advantages of my invention as set iforth. i

Having thus described my invention what I claim as new is K l. An antislipping device for slices elnbodying a lower side chain and an upper side chain for clamping engagement with the upper side of a shoe sole, connecting chains :for said lower andupper side chains, a heel encircling member including bottom chains, and means for resiliently connecting the heel encircling member with the upper side chains.

2.7An anti-slipping device ior shoes ein-V bodying a continuous lower side chain, transverse members connecting the separated portions of said lcontinuous lower side chain, an upper side chain vfor clamping engagement with the upper side of a shoe sole,

3Q Va`heelfencircling member includingbottom chain members, and resilient connections between said heel encircling memberand the upper side chains.

3. In combination with a shoe including heel'of the shoe, vpenetrating points Carried by the plate, transverse chains arranged to extend across the heel and having their terminals secured to the plate, and contractile coil springs having their terminals connected to the terminals of the heel plate and the attaching chain, as and for the purpose Y specified. In testimony whereof I affix my signature 1n presence of two witnesses.
